Zinc-High Copper Rolled Zinc Alloy (Z40301)

Z40301 zinc is an otherwise-unclassified alloy of zinc. It is typically furnished in the as-fabricated (no temper or treatment) condition. It has a moderately low heat capacity and a fairly high ductility relative to other zinc alloys. The graph bars on the material properties cards below compare Z40301 zinc to other zinc alloys (top) and the entire database (bottom).
